Abstract

1,137,438. Arcing-preventing in switches. FENWAL Inc. 20 Oct., 1966 [21 Oct., 1965], No. 46889/66. Heading H1N. An arc-suppressing circuit for a two-position changeover switch 10 includes a solid-state gatecontrolled A.C. switch 22 connected across the switch, a load 18 and an A.C. power source 20. The power terminals 24, 25, of switch 22 are connected to the movable contact 12 and a fixed contact 14 of switch 10, respectively, and the gate terminal 26 is connected to a fixed contact 16 of switch 10. A resistor 28 is connected between terminals 26 and 25 and between fixed contacts 14, 16. Thus switch 22 is conducting only when movable contact 12 is transferring between the fixed contacts 14, 16. Resistor 28 is replaceable by an auto-transformer 30 connected across the source 20. A tap 30a on the winding of the auto-transformer is connected to the gate terminal 26 of switch 22 and to fixed contact 16 of switch 10. Specification 1,137,437 is referred to.
